lt will be obvious that any suitable apparatusinay be utilized to carry out each step and the apparatus usefl in each industry will necessarily vary to meet the several conditions obtaining.

I claim: c

1. A process of treating waste material containing combined carbon including the steps ot' subjecting the material to heat. con ducting oil the resultant gaseous`y material, separating the insoluliile mate-rial from the beat treated product. and contacting the gaseous material with ibo insoluble product.

2. A process of treating 'aste material containing combined carbon, including the steps of subjecting said material to heat of a suliicient intensity to free the coinbined carbon, conducting of? the resulting gaseous material from tbe heat treatment.

separating the carbon in sludge form from the beet treated product, and contacting said sludge with said gaseous material.

3. A process treating waste material containing combined carbon which inclu-des the steps of subjecting said material to heat, ot' a sufficient intensity to vaporize a portion of said Waste material. conducting oif tllegaseous material resulting from said heat 'treatment containing any vaporized material, contacting said gaseous product with a portion of the heat treated .product ,ser

whereby the vaporized materiel is removed from the gaseous product by the heat treated product, and lsubjecting said removed vaporized material and the heat treated' product to further heat, whereby the insoluble product is burned and the removed vaporized material is returned to the cycle.

4. A process of treating waste material containing combined carbon including the steps of subjecting the material to heat, conducting oil the resultant gaseous material, separating' the insoluble inaterialfrom the heat treated product by dissolving therefrom the soluble matter, and contacting said gaseous material with the moist residual material.

process of treating waste material containing combined carbon which includes the steps of freeing said carbon with the production of heated gaseous material, producing a sludge with said carbon, and contacting the heated gaseous material with said sludge.

'6. A process of treating material contain-l ing combined carbon which includes the steps of subjecting said material to heat to free the carbon. conducting oil the resulting gaseous material, dissolving the soluble inatter from said beat treated product .whereby a carbon sludge is formed, contacting said gaseous material with said sludge whereby the values in said gaseous material are removed and said carbon is substantially dried` and utilizing said substantially dry carbon containingl the removed values to produce the heat in the initial step of the process whereby thc carbon is burned and the values are returned to the cycle.

ln testimony whereof7 'l affix my signature.
